They can't TFR the whole damn city on a permanent basis like Washing, DC.
My be that the things are so small (looked that way in the pic) that they will not be a GA altitudes.
I've seen some of these drones that are not much more than radio controlled model aircraft.
No way -- have you ever been to Mouse House and seen how gigantic that airport iss (MSO), for the nominal size of the city? The remote terminals are the size of Burbank Airport -- and there're three or four of them. The main concourse is the size of a moderately-megalomaniacal imperial palace.
Then there's SFO, Orlando-Sanford, another entire airport on the northeast side, that regularly gets an odd mix of feeder-airline and GA traffic mixed in with jumbo excursion operators and leasers (Monarch, Ryan Air) coming in from Europe in 747's and big Airbuses.
